' To (I/Z] (Uh/07H it TIIICI/Z/ concern.-

Be it known that I, HARRY S. MoCoRMAoK,

platens and cooperating paper-feedin New York, in the county of NewYorkand State of New York, have invented certain new and useful Improvementsin Type-Writ ing Machines, of which the following is a specification.

This invention relates to therevolugle evices of type-writing machines.its ject is to facilitate the introduction of paper sheets between theplaten and said feeding devices, which are usually in the form of rollsor yielding fingers pressing against the platen, and particularly tofacilitate the placingof the leading edges of the sheet parallel withthe line of writing that is,.to accurately gage the leading edge of thesheet and to'insure the maintenance of the'sheetin such gaged conditionduring its introduction between the platen and said pressure devices.

The invention. is especially useful when it is desired to insert manysheets in the machine together, as during. manifolding, since they maybe readily placed with their edges even.

and parallel with the printing-line, and so maintained during theirintroduction between the pressure-rolls and the platen. After suchintroduction the sheets are maintained in proper relation by thecooperation of said rolls and platen, while the sheets are left free totake their usual coursein passing cutofthe machine.

In carry ng out my. invention-I provide a paper-clip, which extendsalong the platen and is normally open and inactive during the rotationof the platen, so as to permit continued revolutions of the platenindepend-' ently of the clip. Said clip is preferably provided with aage, against which. the-leading edges of the s eet may be laced. Thenthe clip may be closed upont e sheets and held closed bythepressure-rolls runnin thereon.

After passing said rolls and the ot er paperguiding devices usuallyemployed the clip is opened automatically by means of a spring, whichconstantly tendsto hold the clip open. The clip is preferably carriedaround the platen by. the action of. the platen itself, means beingprovided to cause the clip to be operatively connected to the latenwhenever the clip is closed. For tiis purpose I provide ratchet-wheelsor the like uponv the ends of the platen and cause a pair of catchesthat are mounted upon the ends of the clip to engage said ratchet-wheelswhenever the clip is closed to bcconie disengaged from saidratchet-wheels by the action of said spring in opening the clip.

Other features and advantages will hereinafter appear.

In the accompanying drawings, l igure 1 is a side sectional elevation ofthe platen-frame and platen of an Underwood front-strike type-writingmachine provided with my im provements, the clip being shown inpartlyopen position to receive and gage the leading ed es of thesheets.Fig. 2 shows the clip ful y opened and occupying its normal idleposition back of and below the platen, where it is out of the way. Fi 3is a perspective view of the platen and clip and the latter being shownin open position. Fig. 4 is a perspective fragmentary view of one end ofhe platen, illustrating certain details, the clip being shown open. Fig.4% illustrates diagrammatically the preferred angle formed by thepaper-gage with the surface of the platen. Fig. 5 illustrates the use ofthe clip in intro.- ducing sheets between the platen and thepressure-rolls. Fig. 6 is a diagrammatic sectional view showing the clipclosed and illustrating the compactness of the clip and its mainsupporting-bar, whereby they are well adapted to effect an entrancebetween theplaten and the yielding pressure-rolls without necessitatingthe exercise of undue force in turning the platen. Fig. 7 isaperspective viewof the bar and its revoluble collars or hubs, on whichthe clip is mounted. Fig. 8 is a plan view of the clip and its supports,the clip being'shown closed. F i 9 is an inverted plan view of the clip.Flg. 10 shows the relation of the parts shown in Fig. 8 to the platen.Fig. 11 shows the clip in theposition which it assumes automaticallyafter trated type-bars 1. strike rearwardly aga nst gage for the leadingedges of the sheets, to

naled in the ends of a platen-frame, which.

a set of front rolls 7 press upwardly against Y Hinged upon the ends ofthe bar 1t) by the platen, the guide-plate 5 being formed with suitabletransverse openings through which said rolls 6 and.7 play. The rolls 6and 7 are usually mounted so that they may yield downwardly, all of theparts just described being in common use on said machine. y

Upon the ends of the platen are provided annular recesses or bearings 8to receive loosely a pair of collars or ring-like journals 9, the latterrigidly connected byia bar 10, which extends along the platen and closethereto, which bar is beveled along its rear edge, as at 10*,- Fig. 6,to facilitate its introduction between the platen and the'yieldingpressure-rolls 6 7. The bar has at itsends ears 11, which are fixed. tothe collars 9 in any suitable manner, as by means of screws 12,

. and the entire device, which is seen at Fig. 7

removed from the platen,- remains stationary and idle during therotation of the-platen, ex-

cept during the period when it is coupled to the platen byinstrumentalities hereinafter described.

means of pintles 13 is a papenclip 14 in the form of a thin stripextending along the platen from end. to end thereof close to said bar10. The clip is normally held in openposition, Figs. 2 and 3, by aspring 15. Along its rear edge the clip 'is-bent inwardly at right I Ithe front side of the paper-shelf 4, two of angles reform a ledge 16,which serves as a squarethem to-the platen or to bring them intoparallelism with the printing-line, Fig. 1.

From the opposite edge of the paper-clip exclip resting against a stopin the form of a soft-rubber roll 18, carried upon the end of aspring-arm 19, secured by screws 20 upon these rolls 18 being provided,one at each end of the paper-shelt'4, and each carried upon aspring-arm.

When it is desired to introduce a card or sheet or a series of cards orsheets, the device may be turned to'the Fig. 1 position either bygrasping the freely-rotatable collars 9, .which are knurled for thispurpose, Fig. 3, or by taking hold of finger-pieces 21., formed at theends of the clip, said finger-pieces being longer than the tongues 17.In either way I spring 15.

I upon the framework of said machine.

"position, where the clip is. held partly ope n by therolls in, againstwhich the fingerpieces 21 are pressed by the action of the By this meansthe ledge 16 is brought to a position radial ol the platen to. gage theleading edges of the sheets. l Vhen the clip is brought to thispartially-closed position, there are brought into action two catches 22,one at each end of the to engage the teeth 23 ot apair of ratchet-wheelsprovided upon the ends of the platen,

whereby the platen is temporarily locked to the clip and is enabled. tocarr the clip device bodily around from the ig. 1 position to the Fig.11 position, together with the sheets 25, and it will be observed that,as

hereinbefore stated, the construction of the clip is'such and the entireclip structure lies so close to the platen that the rolls 6 and 7 mayride easily thereover. p

The finger-pieces 21 may be of sufficient length to remain-in contactwith the rolls 18 .until the rolls 6 engage and control the clip andkeep it closed; but in the form of the invention illustratedthe saidfinger-pieces are only of sufficient length to remain in contactwithrolls 18 and hold the clip partly closed until such time in therotation of the platen as the clip enters the narrow space between thelower'part of the paper-shelf 4 and the platen, whereby the clip is'revent-ed from opening. The sheets are all eld bythe clip in theoriginal position to which they were adjusted upon the platen until thesheets are safely introduced between the paper-guiding devices and theplaten, (see Fig. 11,) so that the original alinement or squaring of thesheets upon the platen remain undisturbed. The tongues 17 are engaged bythe rolls 6 7 and also by the usual front paper or card guide 26 (seedotted lines, Figs. 10 and. 11) in the form of a wire loop customarilyprovided After passing said loop'the clip is opened wide by a spring 15,Fig. 1 1, disengaging the catches 22 from the ratchet-wheels 24 andbringing the clip to its idle position and permitting the I said clip toride backuntil arrested by the top of the platen, as seen at Fig. 2, theopen i rolls 18, Fig.2, the alined sheets 25 passingthrough the machinein the usual manner.

The ratchet-wheels 24 are "in the form of flanges formed upon hubs orrings 27, slipped over the heads 28 of the platen, and secured by screws29, Fig. 1. The clip carrying collars 9 are confined between saidratchetplatenand the usual or any suitable-pres, sure devices, which.instrumentalitiesj will' machine.

thereafter hold the sheets to the platen in the usual manner, while theleading edges of the sheets are left freerwithout anything-to interferewith their usual progress out of'the 'Variations may be resorted towithin the scopeof. the invention, and portions of my improvements maybe used Without others. "he gage 16 is preferably given a slight lead oradvance inclination outwardly from the: platen, Fig. 4, so thatthe'outermost" sheets of an inserted pack have originally positions inadvance of the inner sheets neartra distance traveledby the outer sheetsin going around with the platen, so that when the sheets have reachedwriting-positions their leading edges standeven'lor flush with] one.another.
